Answer:

$\dfrac{x}{2}=25.5$

Step-by-step explanation:

Let the number be x.

Peter halves the number and gets an answer of 25.5.

It means,

Half of x equals 25.5. So,

$\dfrac{1}{2}x=25.5$

$\dfrac{x}{2}=25.5$

Hence, the required equation is $\dfrac{x}{2}=25.5$ .

skelet666 [1.2K]

Answer:

$\boxed{ \bold{ \boxed{ \sf{f( - 4) = 1}}}}$

Step-by-step explanation:

Given, f ( x ) = - x - 3

Let's find the value of f ( - 4 )

$\sf{f( - 4) = - ( - 4) - 3}$

We know that , $( - ) \times ( - ) = ( + )$

⇒ $\sf{ 4 - 3}$

Subtract 3 from 4

⇒ $\sf{1}$

Hope I helped!

Best regards!!

What is the equation of a line that contains the points (8, –3) and (–8, 3)?

DerKrebs [107]

Answer:

1. D y = 8

2. C y = −8

Step-by-step explanation:

1.Both points have y-coordinate 8, so the line is horizontal.

A horizontal line has equation y = k

where k is the y-coordinate of all of its points.

The y-coordinate of all points on this line is 8.

Answer: y = 8

2.A line with 0 slope is a horizontal line. All points on a horizontal line have the same y-coordinate.

A horizontal line has equation

y = k

where k is the y-coordinate of all of its points.

The y-coordinate of the given point is -8, so all points must have -8 as the y-coordinate.

Answer: y = -8
